Descriptions

Non-radial measure of technical efficiency of fish farms in Oyo State was examined using Data
Envelopment Analysis (DEA). Use of the non-radial measures to calculate overuse of inputs by
inefficient fish farmers was demonstrated and the potential for reducing inputs used by improving
efficiency was evaluated. Ordinary Least Square (OLS) was then used to determine producer
characteristics that are likely to lead to higher technical efficiencies. Results indicate that the majority of
fish farmers in Oyo State are not producing at the benchmark efficiency level advocated by the industry
and all the determinants of efficiency had the expected sign and influence efficiency positively.
